STYLOG RA PHIC PEN.

SPECIFICATION forming part of Letters Patent No. 233,155, dated October 12, 1880.

Application tiled July 3, 1880.

To all whom it may concern:

Be it known that I, ABRAHAM W. LozrEn, of New York, in the county and State of New York, have invented a vnew and useful Improvement in Fountain-Pens, of which the following is a specification.

Figure l is an enlarged side view, partly in section, of myimproved fountain-pen. Fig. 2 is a longitudinal central section of the pen.

Fig. 3 is a detached side view of the lower part of the pen. Fig. el is an enlarged central section of the lower part of the pen.

My invention is intended to and does obviate many objectionable features now found in the ordinary fountain or stylographic pens, some of which defects are the following: The pens are costly, as the point is tipped with platinum or iridium, which is liable to break off in use and tedious to repair. The spring foreing the writing-point to position is apt to weaken through oxidizing. The ink is not strained before coming into the minute passage near the point and soon clogs the same. The pens break joint near the writing-end and soil the fingers with the ink when opened to be lled and while lling. The top cap must be removed each time to obtain an air pressure, and in order to lill the pen a separate glass filler must be used and carried about in a separate receptacle.

The construction of my improved pen is as follows, reference being had to the drawings: A is the hollow tube, handle, or shell of the pen, provided with screw-threads or joints a and a' at each end, and near the upper end with an outside vsurrounding band, B, of polygonal contour. This band is preferably of rubber, and constitutes a-cushion. It also prevents the pen from rolling when laid down.

Into the tube A, through the upper open end, is inserted the filler C, which is composed ofa tube, b, of smaller diameter than A, and tapering nearly to a point, c, at the lower end, with a small opeuin g there. This tube b, which is preferably of glass, is fastened by a flexible rubber collar, d, at its upper end, to a hollow head, g. This head g has upon it, just above the collar d, a screw or joint, which fits the screw or joint a at the upper end of the tube A, and on the top of this head g is a smaller detachable hollow cap, e, which is inserted (No model.)

into an upwardly-projecting nipple, f, of the head g. The hollow cap e, to prevent leakage through it, is of such shape that any ink which reaches it from within the filler O, if the pen is in inverted position, will gather around an inwardly-projecting tube, It, before it can escape through the central air-hole, t'.

When the filler O, constructed above stated, is taken out of the tube A, it constitutes a convenient ller for supplying the tube A with ink. When in position, as in Fig. 2, the liller, having a continuous air-passage from the top opening, t', to the lower opening, c, admits air to the pen sufficient to allow a free tlow of ink from the lower writing-point of the pen. The cap e prevents ink from liowing into the pocket of the wearer, as stated.

I prefer to provide a groove, j, at the side of the tube j', to permit the ready application of D to fwhile writing without cutting off airsupply.

Within the tube b, l prefer to place two filters, k and l, which are porous, expansive plugs, placed at a distance from each other, and which serve a double purpose. When the filler is placed over a reservoir of ink to be filled, the ink passes through the lower porous plug, Z, and is thereby strained. When the filler is in the tube A, and the pen used, a partial vacuum is created between the two plugs lt and l, thereby slightly retarding the tlow of the ink.

m is a rubber band or other cushion placed around the tube b to prevent it from striking the tube A and lessen the danger of' breaking the tube b, which, as stated, is preferably of glass.

The lower filteringplug, l, is preferably composed of wicking or cord, one end of which is carried down through the aperture c, and then up to and beneath the cushion m. This cord can be drawn out more or less as occasion requires. By jointing the tube b to its head g by the rubber pipe d and providing its lower part with the cushion m all danger of breaking it is avoided.

lf the tube b is made of glass, a graduated scale is preferably marked on it to show the amount of ink within and the amount of writing for which it suflices.

Into the screw a', atthe lower end of the tube IOO A, is screwed the hollow peee or writing-nip plell. (Shownot'largesizeinFig.i.) Through this extends the wire or writing-spindle ii, which serves for the peii-poiiit at 1N, where it emerges from the lower end ot' ll, and which extends upward above the piece 1*), so as to be readily pulled out and reinserted when E is uiiscrcwed. This writingspindle n has coiled around its upper part a spring, o, resting at the lower end upon a sliding tube, p, but free at thc upper end. The tube p is ot' less diameter than the interior ot' tube ll. Into the sliding tube p is screwed a screw, il, through which passes, and into which is soldered, the wire il. \\'hen the wire ii becomes shortened by the wearing ot' its writing'end, by simply' screwing the serew l down ont ot' the tube p the writing-point is kept at proper length t'or writing, or it may be entirely screwed up into the seat beyond the inner opening ot' the pen, s0 as to use the pen as a simple gravity'pen without a spiiidle-poiiit.

The springe holds the tube p upon an inner seat in tube l, unless pressure trom below raises said tube ott' the seat. lnto the iippel end ot' the piece E is screwed another tube, s, which embraces and protects the upper end 0f the wire n, and bears against the upper end ofthe spring o, and thus serves to increase or lessen the force of the spring, as may be necessary. The screw-tube .v contains within it a filter, t, and is made sectional so as to allow the ready removal, cleaning, and replacement of the tilter. \\'hen the piece l" and tube s are fastened together in position acontinuons passage runs through them, making, in conliectioii with the parts already described, a continuous hollow passage t'i'oni end to end ot' the pen as soon as tube pis raised oti' its` seat. The cap l), which tits over the lower end ot' the piece E, protects the wire point ux, ainl has at its bottoni a bed ot' sot't. material, il, against which the point n* can rest.

In theuse ol' my pen l tirst obtain a supply of ink by unscrewing and taking out the complete tiller C. The point eotthis is dipped in the iiik-bottlc and ink is gathered within it by suction or gravity. A supply ot' ink having thus been obtained, the tillerU is reinserted and screwed into its place in the tube A. Upon the cap l) being removedthe pressure of the atmosphere through the opening in the cap-piece e, and the hollow tube I permits the ink to tiow t'reely downward through the entire. apparatus and through the iiltcr 1 therein contained, and around the tube p, when the same is raised, down to the point n", which acts as a penpointand applies the liquid upon the substance wrtteii on.

From the foregoing description the advantages of my improvementsare evident. There need be no unscrewing ot' the, top piece to obtain air-pressure, t'or that comes through the cap-piece e. The tiller U t'or the pen is carried with it or within it, not separately, and l this filler is saved from danger of breaking by the band in and the iiexible collar d. The ink is thoroughlyY filtered at k, l, and t before it reaches the narrow passage near the point. The surrounding band B, by its shape, prevents the pen from rolling.

The distance to which the point n* shall project is perfectly and easily regulated by the screw q and spring o, and thelong upward extension ofthe wire n renders it easily removable from its receptacle. The point at which the pen is tilled is remote from where it is grasped, thus avoiding soiling by the ink. Finally, the wire u may be removed, and the pen used for marking, having as its point the opening through which the wire projected, or the filler (i may be used alone as a markingpen.

The cap e may, in many cases, be dispensed with.

The tube s may be perforated at the sides above the lilter l.

The ink is free to tiow as soon as the style n is pressed upon paper andthe tubep raised of't'its seat. ln the space around the tube p the ink is free to tiow down.
